15 units = length times length minus 2
Length = 5
Width = 2
Perimeter = 16
15 = y * (y -2)
Y = 5
5*2 + 3*2 = 16
5x²-(-2x²) = 7x²
(-3x)-(-x) = (-3x+x)=-2x
(-2)-(10)=-12
7x²-2x-12
14.6666666667
Step-by-step explanation:
2•10=20/1/3=6.66666666667+8 is that but you can write it like 14.6 with _ that on top
